2. Description of the Prior Art

A conventional 4U tower-typed server apparatus only loads thirty-twohard disk units within the apparent surface area of the server apparatusdue to universal constraint of the housing. The housing of the 4U serverapparatus includes eight frames disposed close to each other, and eachframe can load four hard disk units arranged in parallel. The 4U serverapparatus has four hard disk backboards respectively disposed on thesame plane on a rear of the frame, and each hard disk backboard coversscope of two frames. Eight hard disk connectors are disposed on an outersurface of the hard disk backboard side by side, to vertically connectwith the adjacent eight hard disk units at most. A vent hole is formedon position of the hard disk backboard between the adjacent hard diskconnectors for heat dissipation. A power connector and a signalconnector are disposed on an inner surface of the hard disk backboard.The signal connector can be connected to a RAID card for establishingconnection between the hard disk backboard and the RAID card, andfurther can be connected to a mainboard by the cable. The powerconnector is connected to the mainboard by the cable.

Shortcomings of the conventional 4U tower-typed server apparatus is thatthe hard disk units are arranged in the frame side by side to expose thesame edges of the whole hard disk units through the front of the frame,the user can watch all the hard disk units in a front view andconveniently remove or insert one or more hard disk units into theframes, so that an amount of the hard disk unit is constrained by theapparent surface area of the server apparatus. Moreover, circuitallocation space on the hard disk backboard is decreased because of thevent holes, and electronic components are difficult to lay on the harddisk backboard in double-sided product process to detour the vent holes.Therefore, the hard disk backboard of the conventional 4U tower-typedserver apparatus is applied to load eight hard disk units, and hasdrawbacks of huge volume, difficult product process, expensive cost andinconvenient repair and replacement.

Further, the storage unit combining module 34can move down from a top opening of the carrying frame 30 to set intothe carrying frame 30 while the accommodating space 90 is not sealed,and then the top blocking slab 42 is assembled with the two lateralslabs 40 after the storage unit combining module 34 aligns with thecorresponding guiding slot 36 to connect with the RAID card 32. The heatdissipating holes 44 formed on the carrying frame 30 respectively alignwith the storage units 54, and heat generated by each storage unit 54(which can be shown in FIG. 8 to FIG. 11) of the storage unit combiningmodule 34 can be effectively dissipated through the heat dissipatingholes 44 for preferred heat dissipation efficiency.

Besides, the top blocking slab 42 is substantially parallel to thebottom slab 38, and dimensions of the top blocking slab 42 is smallerthan dimensions of the bottom slab 38. The storage units 54 (which canbe shown in FIG. 8 to FIG. 11) of the storage unit combining module 34can be moved into or out of the storage unit moving suit 20 in differentassembling/disassembling directions through the front opening 301 andthe top opening 302 of the carrying frame 30

The RAID card 32 is disposed on a rear of the carrying frame 30, such asthe rear of the accommodating space 90. A plurality of sockets 46 isdisposed on a surface of the RAID card 32 facing the carrying frame 30for connecting with the signal adapter 72 (which can be shown in FIG. 8and FIG. 9) of the storage unit combining module 34, and an amount ofthe socket 46 corresponds to an amount of the storage unit combiningmodule 34. In the embodiment, the RAID card 32 has eight sockets 46, butnot limited to, and the storage unit moving suit 20 can load eightstorage unit combining modules 34 accordingly. A power connector 48 anda signal connector 50 are disposed on the other surface of the RAID card32 opposite to the carrying frame 30. The power connector 48 and thesignal connector 50 are electrically connected to the mainboard 14 bythe flexible cable 88.

Please refer to FIG. 1 to FIG. 11. FIG. 8 is a diagram of the storageunit combining module 34 with the storage unit 54 according to theembodiment of the present invention. FIG. 9 is a diagram of the storageunit combining module 34 without the storage unit 54 according to theembodiment of the present invention. FIG. 10 is a diagram of the storageunit 54 with a storing component 84 according to the embodiment of thepresent invention. FIG. 11 is a diagram of the storage unit 54 withoutthe storing component 84 according to the embodiment of the presentinvention. In the embodiment, each storage unit combining module 34 canload three storage units 54, such as the first storage unit 54A, thesecond storage unit 54B and the third storage unit 54C. The storage unitcombining module 34 includes a base 56, a circuit backboard 58 and thesignal adapter 72. The base 56 includes a first positioning zone 60, asecond positioning zone 62, a third positioning zone 64 and an open zone66, and defines a first inserting direction X and a second insertingdirection Y crossed each other. The first inserting direction X ispreferably perpendicular to the second inserting direction Y As shown inFIG. 9, stretching directions of the first positioning zone 60 and thesecond positioning zone 62 are parallel to the first inserting directionX, and the first positioning zone 60 is neighbored with the secondpositioning zone 62 in the second inserting direction Y, so that thefirst positioning zone 60 and the second positioning zone 62 arerespectively located on an upper position and a lower position. Astretching direction of the third positioning zone 64 is parallel to thesecond inserting direction Y and neighbored with the first positioningzone 60 and the second positioning zone 62 in the first insertingdirection X, so the third positioning zone 64 is located on rear of thefirst positioning zone 60 and the second positioning zone 62, and thestretching direction of the third positioning zone 64 is perpendicularto the stretching directions of the first positioning zone 60 and thesecond positioning zone 62. The open zone 66 is neighbored with thethird positioning zone 64.

The first positioning zone 60, the second positioning zone 62 and thethird positioning zone 64 respectively are dotted patterns marked byarrows shown in FIG. 9. A long side of the positioning zone representsthe lateral side, and a short side of the positioning zone representsthe edge side. It is to say, the rear edge side indicates a lower reach(such like a connecting position) of each positioning zone according tothe inserting direction, and the front edge side indicates an upperreach (such like an entering position) of each positioning zoneaccording to the inserting direction.

The circuit backboard 58 is disposed on the base 56. The circuitbackboard 58 is mainly composed on a first section 68 and a secondsection 70 bent from each other. Two sides of the first section 68respectively face the right lateral side 641 of the third positioningzone 64 and the rear edge sides 602, 622 of the first positioning zone60 and the second positioning zone 62. A side of the second section 70faces the rear edge side 624 (which is different from the right lateralside 641) of the third positioning zone 64. A distal end of the secondsection 70 is located within the open zone 66. The signal adapter 72 isdisposed on the open zone 66 and electrically connected to the secondsection 70 for connecting with the corresponding socket 46 of the RAIDcard 32. In another embodiment of the present invention, the RAID card32 can be parallel to the bottom slab 38 and the signal adapter 72 movesdownward to insert into the corresponding socket 46 of the RAID card 32.Generally, dimensions of the first positioning zone 60, the secondpositioning zone 62 and the third positioning zone 64 are identical, alength of the first section 68 may be shorter than a length of thesecond section 70, so that the circuit backboard 58 can be a L-shapedslab component, the first section 68 is a long section of the L-shapedslab component (the circuit backboard 58), and the second section 70 isa short section of the L-shaped slab component (the circuit backboard58).

The circuit backboard 58 further includes a first connector 74, a secondconnector 76 and a third connector 78. The first connector 74 isdisposed on a position of the first section 68 facing the firstpositioning zone 60. The second connector 76 is disposed on a positionof the first section 68 facing the second positioning zone 62. The thirdconnector 78 is disposed on a position of the second section 70 facingthe third positioning zone 64. The first connector 74, the secondconnector 76 and the third connector 78 respectively are mid-mountconnectors. The base 56 further can include a plurality of constrainingcomponents 80 respectively disposed on two opposite lateral sides of thefirst positioning zone 60, the second positioning zone 62 and the thirdpositioning zone 64. The constraining components 80 of the positionzones 60, 62, 64 are utilized to constrain a movement of the relatedstorage units 54, which means the first storage unit 54A, the secondstorage unit 54B and the third storage unit 54C can be slidablyassembled with or disassembled from the base 56 through the firstpositioning zone 60, the second positioning zone 62 and the thirdpositioning zone 64 in the first inserting direction X and the secondinserting direction Y, respectively.

As shown in FIG. 8 and FIG. 9, the first storage unit 54A and the secondstorage unit 54B are assembled with the first positioning zone 60 andthe second positioning zone 62 in the first inserting direction X, andrespectively connected to the first connector 74 and the secondconnector 76. The third storage unit 54C is assembled with the thirdpositioning zone 64 in the second inserting direction Y different fromthe first inserting direction X, and connected to the third connector 78accordingly. Thus, the first inserting direction X is substantiallyperpendicular to the second inserting direction Y the stretchingdirection of the first section 68 can be substantially parallel to thesecond inserting direction Y, and the stretching direction of the secondsection 70 can be substantially parallel to the first insertingdirection X.

As shown in FIG. 10 and FIG. 11, the storage unit 54 may include asupporting component 82, a storing component 84 and a detachingcomponent 86. The storing component 84 can be a 2.5-inch hard disk, butnot limited to, fixed on the supporting component 82. The detachingcomponent 86 is disposed on an end of the supporting component 82. Whilethe storage unit 54 slides into the base 56 via the constrainingcomponent 80, the detaching component 86 can be engaged with the base 56to constrain a relative movement between the supporting component 82 andthe constraining component 80, so as to prevent the storage unit 54 frombeing disassembled from the base 56. For repair and/or replacement ofthe storage unit 54, the detaching component 86 can be activated tounlock connection modes of the rear connectors 74, 76, 78, so as todisassemble the storage unit 54 from the positioning zone of the base56. For instance, the first storage unit 54A and the second storage unit54B can be pulled out of the carrying frame 30 through the front opening301, and the third storage unit 54C can be pulled out of the carryingframe 30 through the top opening 302 for conveniently replacing thestoring component 84, as shown in FIG. 4 to FIG. 7.

In conclusion, the housing 12 of the server apparatus 10 preferably canbe universal standard, so that two storage unit moving suits 20 areloaded inside the bridging frame 18, and eight storage unit combiningmodules 34 are disposed inside each storage unit moving suit 20. Thestorage unit moving suit 20 is electrically connected to the mainboard14 by the flexible cable 88, and the storage unit moving suit 20 can bepulled out of the bridging frame 18 via the slide rail structure 28while the server apparatus 10 is in normal operation. The storage unitcombining modules 34 are vertically disposed inside the storage unitmoving suit 20 side by side. A gap is formed between the adjacentstorage unit combining modules 34 for passing through the coolingairflow. The heat dissipating holes 44 on the carrying frame 30respectively align with the storage units 54 of the storage unitcombining modules 34 for preferred heat dissipation efficiency, and thestorage unit combining module 34 of the present invention does not formvent holes on the circuit backboard 58 in the present invention.

For matching with the L-shaped circuit backboard 58 without the ventholes, the base 56 of the storage unit combining module 34 are dividedinto the first positioning zone 60, the second positioning zone 62 andthe third positioning zone 64, and the L-shaped circuit backboard 58 islocated between the first positioning zone 60, the second positioningzone 62 and the third positioning zone 64. The first storage unit 54Aand the second storage unit 54B can be transversely inserted into thefirst positioning zone 60 and the second positioning zone 62 in thefirst inserting direction X, the third storage unit 54C can bevertically inserted into the third positioning zone 64 in the secondinserting direction Y, and first storage unit 54A, the second storageunit 54B and the third storage unit 54C are respectively connected withthe first connector 74, the second connector 76 and the third connector78 of the L-shaped circuit backboard 58 to establish connection of themainboard 14 via the RAID card 32; therefore, the storage unit combiningmodule 34 can dispose the third storage unit 54C on redundant spacebetween the bridging frame 18 and the heat dissipating module 16.Because each of the bridging frames 18 can load two storage unit movingsuits 20, each of the storage unit moving suits 20 can load eightstorage unit combining modules 34, and each of the storage unitcombining modules 34 can load three storage units 54, so that thestorage unit moving suit 20 has twenty-four storage units 54 at most andthe server apparatus 10 can simultaneously have forty-eight storageunits 54. The present invention increases loading amounts of the storageunit 54 without changing volume and specification of the serverapparatus 10. The present invention is not limited to theabove-mentioned embodiment that the bridging frames 18 has two storageunit moving suits 20 and the storage unit moving suit 20 has eightstorage unit combining modules 34, and further can be applied to theserver apparatus with one or more than two storage unit moving suits, orapplied to the server apparatus that includes the single storage unitmoving suit having the storage unit combining module with other numeral.

Comparing to the prior art, the storage unit combining module and therelated storage unit moving suit of the present invention can increasethe loading amounts of the storage unit while volume of the serverapparatus is unvaried. The circuit backboard of the storage unitcombining module does not have the vent holes to increase circuitallocation space on the circuit backboard. The hard disk connector, thepower connector and the signal connector are not disposed on twosurfaces of the circuit backboard, and the single-sided product processcan be applied to effectively economize manufacture cost of the circuitbackboard. The storage unit moving suit is connected to the mainboard bythe flexible cable, so the storage unit moving suit can be pulled outand pushed into the housing for replacement of the storage units whilethe server apparatus is in normal operation. Each storage unit combiningmodule is matched with three storage units, and a quantity of the harddisks within the server apparatus can be highly changeable forcustomized demand.

Those skilled in the art will readily observe that numerousmodifications and alterations of the device and method may be made whileretaining the teachings of the invention. Accordingly, the abovedisclosure should be construed as limited only by the metes and boundsof the appended claims.
